Untouchable: A Closer Look At Nadaka’s Unbeaten Run In ONE Championship
Reigning ONE Atomweight Muay Thai World Champion Nadaka is a generational talent whose mastery inside the ring transcends eras.
The Japanese phenom stands as the archetype of a complete striker, seamlessly fusing speed, precision, and fight-ending power. Yet beyond his physical gifts, his elite fight IQ and mental fortitude separate him from his peers.
As the only non-Thai athlete in history to simultaneously hold the coveted Lumpinee and Rajadamnern Stadium World Titles, the Japanese superstar boasts a 67-6 professional record.
Having not lost a bout in over six years, his five consecutive victories against the elite in ONE Championship have stretched that remarkable run to an astonishing 41 straight wins.
Nadaka now looks to conquer new territory when he steps into the world of kickboxing for the first time against Har Ling Om at ONE SAMURAI 3 on September 12, streamed live from Yokohama Buntai. Just a month later, the defending champion returns to defend his Muay Thai crown against Rifdean “Magic Boy” Masdor at ONE SAMURAI 4 on October 17 inside Tokyo’s Ariake Arena.
Ahead of this ambitious two-sport schedule, let’s retrace the unblemished steps of Nadaka’s ONE tenure.
Introducing A Phenom
Making his highly anticipated promotional debut, Nadaka wasted no time proving he belonged in the world’s largest martial arts organization at ONE 172 in 2025.
The Yokosuka native squared off against former Lumpinee Stadium champion Rak Erawan in front of a passionate home crowd at Saitama Super Arena. Rather than feeling things out, he showcased his dynamic striking arsenal from the opening bell.
After two tactical rounds built on sharp angles and clean counters, Nadaka slipped a Rak advance in round three and connected with an expertly timed straight left at the 2:40 mark.
The perfectly placed shot knocked Rak out cold with 20 seconds left on the clock, instantly validating the hype that preceded him.
Precision More Than Power
With the global fanbase still buzzing from the knockout of Rak Erawan, Nadaka made a quick turnaround against Banluelok Sitwatcharachai, a dangerous finisher carrying a flawless 3-0 ONE run.
Faced with heavy power at ONE Friday Fights 114, the Eiwa Sports Gym product used elite footwork and feints to neutralize his opponent’s traditional rhythm.
Nadaka shifted gears with beautifully timed combinations. By the third frame, his multi-layered output had worn through the Thai veteran’s guard.
Coasting to a clear-cut unanimous decision victory, the Japanese striker handed Banluelok his first promotional loss, proving he was already a name to fear.
Building Toward Gold
With two flawless victories under his belt, Nadaka sought his third promotional win against Hamada “Black Panther” Azmani at ONE Friday Fights 122.
Utilizing his timing and sharp counters, the 25-year-old systematically broke down the Spanish-Moroccan striker, dropping him twice during the affair.
Sensing the finish, Nadaka overwhelmed his dazed opponent with an unrelenting sequence of strikes, forcing the referee stoppage just 15 seconds into round three.
The technical masterclass secured a TKO victory and positioned Nadaka for a shot at 26 pounds of gold.
Making History On Home Soil
That undeniable case for greatness set the stage for ONE 173 at Tokyo’s Ariake Arena. With the inaugural ONE Atomweight Muay Thai World Championship on the line, Nadaka battled surging Thai slugger Numsurin Chor Ketwina and his spotless 6-0 promotional record.
From the opening bell, the hometown hero controlled the action with slick feints that lured Numsurin into poorly timed counters.
Nadaka landed a sharp left straight late in round one, and although Numsurin rallied briefly in the second stanza, the Japanese star remained frustratingly elusive.
By the championship rounds, Nadaka’s suffocating volume and distance control left Numsurin with nowhere to go. All three judges scored it clean, crowning Nadaka the first-ever ONE Atomweight Muay Thai World Champion.
The True Test Of A King
Now the reigning king, Nadaka made his first World Title defense against Songchainoi Kiatsongrit at ONE SAMURAI 1 this past April. Nadaka had stopped the Thai star outside the promotion three years prior, but this time, he faced a dramatically evolved challenger armed with a 10-1 ONE record.
The rematch quickly became the most competitive bout of the Japanese superstar’s ONE tenure. Songchainoi pressed forward with heavy clinch work and overhand rights, eventually opening a cut on the champion’s face.
Pushed to his limits, Nadaka leaned on his fight IQ to weather the storm. He doubled up on his kicks to control the distance and utilized masterfully timed clinch defense to survive a fifth-round rally.
Retaining his crown via unanimous decision, the champion proved he possessed the grit required to conquer the toughest of tests.
With his World Title defended and his spirit proven, Nadaka now prepares to tackle two sports and further cement his legacy.
